A ceiling coming down, and the pipe that was doing it

A tenant reported a ceiling tearing from old water damage. The cause was a corroded cast-iron waste line under a tub in the apartment above.

What causes a brown stain on a ceiling that keeps coming back?

Something above it is still wet. A ceiling stain is the last place water arrives, not the first place it appears, so patching and repainting it treats the symptom and buys a few months. In this case the ceiling was in one apartment and the cause was a corroded cast-iron waste line under the tub in the apartment above — which means the repair needed access to a second property and a second tenant, and the drywall could not go back until the line was proven. We open it up and show you rather than tidy it out of sight.

The problem

A tenant reported the ceiling tearing away from old water damage. The unit had been patched before. Opening it up found a cast-iron waste line serving the tub in the apartment above, badly corroded at the joints, still leaking — which is why the stain had come back every time somebody painted it.

What it took

Two units, two access appointments and a hold on the drywall until the line ran dry. There was no charge for the return visit.

What was done

  • Ceiling opened up at the stain to see what was actually above it
  • Leak traced upward to the tub waste in the unit above, not the unit reporting it
  • Corroded cast-iron section identified and the line test-run before anything was closed
  • Failing section replaced
  • An access panel recommended at that point, so the next inspection of that joint does not need a new hole cut in a new ceiling
  • Drywall made good and finished only after the line was proven dry

The outcome

A stain that stops coming back, because the thing making it was replaced rather than painted over. The tenant who reported it was not the tenant whose plumbing caused it — which is the part that makes this a property-manager job rather than a one-visit repair, and the reason it took two access appointments in two homes.
